There are some basics to business success for leaders and one of them is flexibility. I would equate "learning agility" to that attribute. If a leader can't be flexible to the changing times/processes/new techniques, then he will not be successful for long. If an alleged leader still depends on pen and paper without recognizing the absolute need for the internet/new technology/communications, then he is not long for success in the current environment.

More important than the need to "know how to know" is the need to find out what you don't know.

There is a limit to uninitiated self learning. It is too much of an arrogance that one can learn
anything at any time when needed. Learning agility is a quality no doubt but that always belong to a learned man.

Yes, as long as it is something that gives one meaning the learning becomes a curiosity and often fun.
